Asus TF300T and Ubuntu Sync

I have a quick question to everyone who has the TF300T and Linux. Have you been able to plug in the tablet directly in Linux (Ubuntu)and open the filesystem to transfer files? it seems that in windows I need to have that Asus Sync program, but i would rather not use a program. I would imagine it would be a plug and play situation.
I would appreciate to read how to go around that.
Thank you in advance.

I have windows and it is plug and play for me. I never downloaded the ASUS Sync program. I just plugged it in and it recognized the internal sdcard with no problems at all.

I'm on windows and i've never needed to use the asus sync program. I just connect my tablet to the computer and it pops up as a usb mass storage device.

Interesting. I am at work now and we are using Vista. I have it plugged in and on the device it says "Connected as a media device" and then nothing comes up. Also i have that Asus Sync icon in the notification area

I use Windows 7 Enterprise at home and it works for me
I don't have a issue with this at home.
Once I plug it in, a USB menu opens and verifies that it found a new device.
The issue you may be having is with in Vista itself.
I'm using Windows 7 Enterprise, and I can view all the files on my Asus, I don't even have Root yet. That whole .26 thing!
I just fired up a Ubuntu system at work to try to get around the issues with ADB on a Windows 7 64 bit system, so I can try to downgrade it to .17, root, load root keeper, then try the OTA update to .26. Have not quite got there yet though.
So far this has all been a complete pain on Windows, the ADB software comes to a screeching halt do to a Java issue, that no one can see to correct on my O.S.
Would be nice if some one just put out a 1 click Root app like I had on my DrodX!

i think i could depend on the drivers.
but dont expect an USB drive to appear as an HD or removable device, as it is MTP, you have to access the files via the DEVICE ICON that appears on the computer folder.
i dont know if its the same on vista. but as win 7 is Vista + it shouldn't be too different.

Ubuntu user here.
Yes I was/am able to get it connected and able to get files on it but not without some extra work.
I mostly followed the following site and changed some of the names he gave his phone into TF300.
(being a new user I am not able to post url links and am not able to post in de development site yet...damn)
Do a google search on: omg ubuntu android usb drive
and the first hit is the site.
After having done that, all it takes to have it seen as a drive is enter <android-connect> into a terminal. (and <android-disconnect> to shut off cleanly).
It's only seeing the sdcard, not / (hoped for an easy root access ).

Need Help! Deleted Photo Album (Baby pics missing)

I can't believe I did it, must of accidentally deleted photo album. Stayed up for hours last night and all of this morning trying to find a way to recover the album. I have a bunch of my daughter's pics in that album and I really need them back.
I have a Nexus 4 with 4.4.2 loaded on it and the phone is not rooted. I have been trying to find a way to root the phone without wiping the data so I can try to use diskdigger to recover what I can. I don't know if there is a way with this version, but if there is and you know, please post. If you can show me a way and it is successful you will have some paypal money coming your way. Thanks in advance!

My first response would be to use disk digger like you said, but as much as rooting is a wonderful thing, I don't think it is needed in this case.
Disk digger is actually derived from a desktop app of the same name, that does the same thing with desktop and laptop hard drives.
Web page here
http://diskdigger.org/
If you connect your phone to your computer as external storage then you should be able to run the program on the computer but targeted at your phone, hence recovering your lost files.
Note: if this works then LOTS of files will be found, (including ones you never knew were even on your phone) so be prepared to search through them all.
I really hope this helps, I know what it is like to loose precious files, safe to say you should backup everything valuable from hereon
Let me know what happens either way and I will try and help if it does not work

yeah, just tried the pc software for diskdigger, phone doesn't show in list. Has a advanced tab, but only lets you choose .vhd files it looks like. If only you could get the phone into a vhd.

OK, so the first question is if the phone is mounted correctly, does it show in 'my computer' and when double clicked on can you see files?
Next question is if you are using the .exe correctly, take a look at this tutorial: http://diskdigger.org/node/1025
I'm sorry if this sounds condescending, but I don't know your experience with computers

LOL...no problem. Been a systems admin for about 10 years. Anywho, yeah, this is the nexus 4 so it only has internal memory, no sd card. I can see the phone in my computer, but there is no drive letter assigned, apparently that changed in 4.3 up through 4.4.2, which I am on. So what that means is no mass storage option where drive letter gets assigned, so routine recovery software can't read it as an attached drive.

Hmmm, you should still be able to mount as external storage, I have done so before on that android version.
First thing then is if USB debugging is enabled, this will be in your settings under developer options and should not require root.
Then it is a question of whether your computers drivers are correct, android has a tendency of not liking to do drivers correctly, I used PDAnet to install the correct USB drivers (note these are different to the ADB drivers which you don't need)
Get back to me with the results of those 2 points

Yeah, I had developer options enabled and USB Debugging mode on, maybe it could be a driver issue. I tried PDAnet and that didn't seem to update the drivers for the phone. The device shows okay in device manager, no exclamation point, shows as Nexus 4 as well and the driver seems to be a Microsoft driver. Are you sure you had the same android version? Everywhere I look any version after 4.2.2 cannot be used as a mass storage device because of the MTP-PTP change in 4.3 and 4.4.

I am on 4.4.3 now, and have the phone connected fine right now, have you tried switching between MTP and PTP?
Note: I am on MTP and it is working.
I am sure there is a problem with something to do with connecting your nexus to the computer, as mine is doing so right now. If we can resolve that issue and access the internal storage then you should be able to then recover the files with disk digger.
My best guess would be a driver issue as android has never really played well when trying to set up drivers. But like you said the computer is recognising it correctly. I think perhaps testing the drivers connection my be the next step, use ADB with the command 'adb devices' (without quotes) to see the devices connected to the adb server. If nothing comes up then we may be able to start troubleshooting :good:
Perhaps ADB is the difference, i have it installed and sorted, do you?
If you have never used ADB before, here is a good place to get started and here is another mention of the drivers, perhaps another attempt may be worth a try, with a clean intall
Safe to say in my drivers list it is connected under android device > android composite ADB interface.
Actually yes, thinking about what i have just written i am confident it is ADB and drivers, you should not be connected with Microsoft drivers, they are the automatically installed ones and never work. Follow the guides above (and perhaps some googling) to get the proper drivers and ADB set up, once you think you have test it with the 'adb devises' command, once you get it returning a serial number for your phone then take a look in 'My Computer' again and see if the storage is visible.

nexus 4 only support MTP, not USB Mass Storage, so can't be mounted with a drive letter and can't be used with undelete software . If you know any working solution without root - please tell us, but test first yourself before writing please
P.S. you are on 4.4.3 ?

My most sincere apologies, i was mistaking the mounted MTP device for the mounted drive, i now see what you mean.
In this case rooting is your only option, you need to run the file recovery natively.
I had hoped that this would not be necessary as unfortunately the rooting process will perform a lot of write operations so you must be prepared for some of your images to become corrupted or incomplete, (hence why i wanted to attempt other options) this is just the risk that you will have to face. How many will be damaged is difficult to say.
So use one of the many tool-kits or root manually, install the disk digger APK and you are good to go.

to root you will need to unlock phone bootloader and that will wipe all your device ...

[Q] Mojo won't connect to PC and lacks sound! Help!

So i just got my MOJO and was in the process of rooting it but, i can't seem to get windows 7 to recognize the device when i connect it by USB. It always shows up as "unknown device". How do i get Windows 7 to recognize it?
Also i have another problem regarding sound....there isn't any. When i load up a video on the MOJO, or just try to do anything that would have sound, theres nothing. I have the sound at MAX using the CTRL gamepad controls. Still, nothing.
I knew the MOJO was going to be one of those devices you have to fight with in order to get it to do what you want but, this is worse than i expected.
Help?

It really is a terrible experience out of the box. We know who to blame Mad Catz!

For Windows to recognize it, you have to install ADB Drivers, try the ones from teamandroid: www teamandroid .com/download-android-usb-drivers/
You will have to locate the device in the windows device manager and install the drivers manually.
But you can root the mojo without conencting it to the pc. you can root it with towelroot (Version 1). you have to search with google for the apk. the newest version (3) and v2 won't work.
After that you can use Flashify to flash a custom recovery.
For the sound: do you have another hdmi slot at your tv? this sounds like a connection problem.

Connecting it to the PC is (supposed)to be the EASY way though. Also....i don't see the mojo listed among the devices on that link you mentioned. Which one should i download??

Try the driver from Samsung.
If they don't work, use the universal adb drivers: github.com/koush/UniversalAdbDriver
Towelroot would be much easier, you just install the App and klick one button (but only v1 works with mojo)

Thanks for the reply but i've tried all towelroot 1.0 as well as 3.0 and it did NOT work. I got an error saying, "This phone isn't currently supported". No matter which version i try.
Edit: Ok got it working! Turns out i was attempting the V2.0 & V3.0 versions. There are plenty of sites out there that would claim to have v1.0. However, once i downloaded and installed it, i'd see a "v2" or "v3" at the top of the screen.
In the end, I had to do a google search for a towelroot spefically for MOJO. Only then did i finally come across a site that had a legit v1.0.

Good job! I'm glad it worked in the end.
I also had to search a long time to find the correct tr version. But you will never need it again, once it's rooted. if you want to go back to stock, you can flash the original firmware with twrp, too!

Here was the thread it was in:

And the link for V1.0 in case anyone wants it. It was tough to find:

Ok so after a few hard weeks messing with this device, i've figured out ways to fix all its quirks, except for one: Not being able to connect to Pc. Thats annoying. I don't like having to remove my Micro SD card everytime i want to add more files.
Especially since this device was deigned in such a way that, its virtually impossible to remove without first removing the HDMI cable first. As they are sooooo CLOSE together.
Any suggestions for drivers? I just need it to function like a plain USB mass storage device, so i can access my Micro SD card on the Pc.

Yeah, the microSD is a pain to remove.. but I never need to touch it.
I don't understand why you want to access the SD via PC as a USB device?
To access the sdcard over wifi I use a SambaDroid server on the mojo pointed to the sdcard.. it works.

I want to be able to freely connect my MOJO by USB and drag & drop files at will to the Micro SD, without having to physically remove the Micro SD card each time (which also means unplugging the HDMI every time!!).
So far i'm enjoying the MOJO console as i've found fixes for every other problem i've run into. This is the only one that continues to elude me. I had not thought about the possibility of my Pc being able to connect remotely though wi-fi, to access the MOJO storage. This might be yet another out-of-the-box fix for me. Can you explain more about how this is done??

Not sure why you want to have a USB on the MOJO that way... the idea of MOJO(or any other topset box) is to keep it online next to your TV, I used to plug USB thumb drives into it.. but you never want to change microSD cards.. same like on a phone or tablet really.
Just install this on mojo:
https://play.google.com/store/apps/details?id=berserker.android.apps.sambadroid&hl=en
You can configure it so it shares a folder (google how to share folders on windows or youtube sambadroid).
You can use just the microSD (i think it's /mnt/card1) or the internal storage(i think /storage) or both using just /
I wouldn't do just / though.
It's pretty easy, just replicates windows file sharing and works well.

How to disable automount of the USB Drivers on Windows

I'll be darned if I can find an answer on this, which is weird, because I was able to 'fix' this on three prior phones.
When you connect (to Windows 7 PC in my case) via USB, the system detects and mounts a new USB drive (as a drive letter device) and pops up an Autoplay window. If allowed, it will install the drivers. Handy? The first time, yes. Many times later? Lightly annoying. *shrug*
Who's got the skinny on a solution for this "issue". LOL

Me! You'll need to have root access though. All you need to do is delete the /system/etc/usb_drivers.iso file and you're done.

Do copy before. If you lose those drivers you need to look for them on internet, there is no official drivers or I couldn't find them. What about disable autoplay from usb on Windows.

I renamed, adding .bak to the filename. Seems to have worked. (After I otherwise solved my problem with access to root files that ES File Manager couldn't grant access to, that is. Solid Explorer FTW)
I looked at Windows-side options, but I needed to solve the root access problem anyway, so... Also, I wanted to disable it for just this volume and it was unclear how feasible it would be for a single volume. I think I saw something about it being able to be on a per-volume (using unique ID) but didn't dig very far.

Tab S2 (813) SD Card Not Seen by Windows 10

Howdy, folks. Had a T813 for about a half year now, but have not done anything in the way of a custom ROM - I just rooted the stock MM firmware and ran with it.
I'd like to now put a Nougat ROM on the machine, but for some reason, Windows is not mounting the SD card in the tablet. There are some files I'd like to archive just in case things go "big-bad". If you have any insight, please point me in the right direction?
Also, since I haven't yet flashed TWRP on this machine, any warnings or guides would be appreciated.
Thanks in advance!

Yep. That's the driver I installed. But no go. I'm not seeing the USB/Charge option.
My plan is to flash the tablet with another ROM anyway. Right now, I'm stock rooted with (if memory serves) CF Autoroot. So, can I use Odin (or something else) to offload my data until I get to where I want to be?

I've had this same issue at times with various devices. Fixes that have worked for me are:
1. Try a different USB port on your computer. In my case my ports on the front were not working but the back ports worked fine.
2. Try a different cable. I had one fail just this past week.
3. Find the drivers on your PC and delete them manually, then reinstall from scratch. Not sure why this worked but it did in a couple of cases.
Worst case you can remove your SD card and plug it directly into your PC, then copy any files between that you need to save. Also, just asking the obvious here, do you have "USB debugging" turned on in Developer Options? I am assuming you do but ya never know.
